ABSTRACT:
A stepwise brake control is automatically performed when TTC obtained according to a relative distance and a relative speed between a vehicle and an object is lower than a predetermined value. For example, a brake force or a brake reduction speed is gradually increased over a plurality of stages in time series. Moreover, the affect of speed change control to the automatic brake control is removed. Alternatively, automatic brake control is supported by the speed change control. Alternatively, the friction coefficient state is estimated, and the brake force or the brake speed reduction is adjusted according to the estimated result. Alternatively, an auto-cruse function is invalidated at least the final stage. Alternatively, when the brake force or the brake speed reduction generated by a brake operation by a driver is greater than the brake force or the brake speed reduction generated by the brake control means, the brake operation by the driver is handled with a higher priority than the stepwise brake control.
